by when to expect the docs on PHP 4.0.4 ?

Hi, I just upgraded my PHP 4.0.3pl1 to PHP 4.0.4 - everything went perfect. And, I am now quite interested in the new functions such as is_null(), get_defined_functions(), get_defined_vars() and constant(). I would also love to read more about three expressions and object by reference things. Is it already documented somewhere or if not yet then by when approximately should I expect it?
